Fixed inductors are components that store electrical energy in the form of an inductor. They come in many different forms, from dust-size to large chunks of metal. One common application of these inductors is in the 4470R-18G, a Power Supply-grade part.These 4470R-18G inductors exist within a range of alternatives, including 4470R-21G, 4470R-25G, 4470R-28G, and 4470R-29G. Although their sizes, structures, and properties differ from each other, all of them are used for the same purpose: providing parts with the most efficient and reliable electronic energy transfer.The 4470R-18G inductor is ideal for applications that require high-capacity power dissipations, such as motor drive circuits, power supplies, switching power supplies, power converters, and inverters. This inductor has a flat configuration and uses ferrite cores, making it an ideal choice for PCB applications where space is limited. It also offers increased reliability and performance due to its epoxy encapsulation and superior magnetic properties.The 4470R-18G\'s performance is made possible by its working principle. Electromagnetism, which is the branch of physics that studies the relationship between electric and magnetic fields, serves as the basis of the operating principle of an inductor. When an electric current passes through an inductor, a varying magnetic field is produced. This varying magnetic field in turn creates an electric field that interacts with the electric current, creating a back-EMF (electromotive force).The result is that the increasing current flow causes a greater magnetic field and stronger electric field, which reduces the speed of the current flow, resulting in what is called "inductor action." As the current flow decreases, so does the back-EMF, allowing the current to flow faster again and resulting in the inductor\'s self-regulating effect.In the case of the 4470R-18G, this self-regulated effect allows the inductor to provide higher efficiency and reliability. This performance is further enhanced by its flat configuration and ferrite cores, which provide greater thermal stability and increased magnetic properties. The epoxy encapsulation also ensures that the inductor is kept safe from extreme temperatures, moisture, dust, and other damaging attributes.Overall, the 4470R-18G is a highly reliable and efficient fixed inductor that is ideal for applications that require high-capacity power dissipations. Its well-crafted design and sophisticated engineering principles enable the inductor to provide high-performance and reliability, making it a great choice for those looking for a power supply-grade part.
